How to add a content marker pointer in the .NET MAUI Linear Gauge (SfLinearGauge)?

In the Syncfusion® .NET MAUI Linear Gauge (SfLinearGauge), you can add a Content Marker Pointer to enhance your gauge display. This guide will demonstrate how to implement this feature using both XAML and C# code examples.

XAML:
The SfLinearGauge’s LinearContentPointer allows you to utilize any .NET MAUI content as a marker pointer. The label in the following code example is used as a marker pointer.

<gauge:SfLinearGauge VerticalOptions="Center" WidthRequest="600">
   <gauge:SfLinearGauge.MarkerPointers>
       <gauge:LinearContentPointer Value="30"  IsInteractive="True"
                                   ValueChanged="Pointer_ValueChanged"
                                   Position="Cross">
           <gauge:LinearContentPointer.Content>
               <Grid HeightRequest="32" WidthRequest="32">
                   <Ellipse Fill="#ff0074E3" HeightRequest="32" WidthRequest="32"/>
                   <Label Text="30" x:Name="textPointerLabel"
                          FontAttributes="Bold" HorizontalOptions="Center"
                          VerticalOptions="Center" TextColor="White"/>
               </Grid>
           </gauge:LinearContentPointer.Content>
       </gauge:LinearContentPointer>
   </gauge:SfLinearGauge.MarkerPointers>
</gauge:SfLinearGauge>

C#:

Set the label value using the ValueChanged Event handler.

private void Pointer_ValueChanged(object sender, Syncfusion.Maui.Gauges.ValueChangedEventArgs e)
{
   textPointerLabel.Text = ((int)e.Value).ToString();
}

Output:
